INSTALLATION
LOCATION
It is extremely important to install the compressor in a clean, well ventilated area where the surrounding air temperature wi ll not be more
than 100° F.
A minimum clearance of 18 inchesbetween the compressor and a wall is required because objectscould obstruct airflow.
CAUTION
Do not locate the compressor air inlet near steam, paint spray, sandblast areas or any other source of contamination. This debris will damage
the motor.
ELECTRICAL INSTALLATION
WARNING
All wiring and electrical connections should be performed performed by a qualified electrician. Installation must be in accordance with local
codes and national electrical codes.
CAUTION!
Never use an extension cord with this product Use additional air hose instead of an extension cord to avoid power loss and pe rmanent
motor damage; Use of an extension cord voids the warranty.
GROUNDING INSTRUCTIONS.
1. This product is for use on a nominal 230 volt circuit and has a grounding plug that looks like the plug illustrated in Fig.3.Make sure the
product is connected to an outlet having the same configuration as the plug. This product must be grounded. In the event of a n electrical
short circuit, grounding reduces risk of electrical shock by providing an escape wire for electric current. This product is equipped with a cord
having a grounding wire with an appropriate grounding wire with an appropriate grounding plug. Plug must be plugged into an o utlet that is
properly installed and grounded in accordance with all local codes and ordinances.
DANGER!
Improper use of grounding plug can result in a possible risk of electrical shock!
DANGER!
Do not use a grounding adapter with this product!
2. If repair or replacement of cord or plug is necessary, do not connect grounding wire to either flat blade terminal. The wire with insulation
having an external surface that is green (with or without yellow stripes)is the grounding wire.
Never connect green(or green and yellow) wire to a live terminal.
3. Check with a qualified electrician or serviceman if grounding instructions air not completely understood, or if in doubt as t o whether
product is properly grounded. Do not modify plug provided; if it will not fit outlet, have proper outlet installed by a qualified electrician.
4.
WARNING!
1. Local electrical wiring codes differ from area to area. Source wiring, plug and protector must be rated for at least the ampe rage and
voltage indicated on motor nameplate, and meet all electrical codesfor this minimum,
2. Use a slow blow fuse or a circuit breaker.

OPERATION
Pressure Switch-Auto/Off Switch-In the AUTO position, the compressor shuts off automatically when tank pressure reaches the maximum
preset pressure. In the OFF position, the compressor will not operate. This switch should be in the OFF position when connecting or
disconnecting the power cord from the electrical outlet or when changing air tools.
Regulator-The regulator controls the amount of air pressure released at the hose outlet.
Safety Valve-This valve automatically releases air if the tank pressure exceeds the preset maximum.
Discharge Tube-This tube carries compressed air from the pump to the check valve. This tube becomes very hot during use. To avoid the
risk of severe bums, never touch the discharge tube. Check Valve-A one-way valve that allows air to enter the tank, but prevents air in the
tank from flowing back into the compressor pump. Handle-Designed to move the compressor.
▲WARNING!
Never use the handle on wheeled units to lift the unit completely off the ground.
Drain Petcock-This valve is located on the bottom of the tank. Use this valve to drain moisture from the tank daily to reduce the risk of
corrosion.
Reduce tank pressure below 10 psi, and then drain moisture from tank daily to avoid tank corrosion. Drain moisture from tank by opening
the drain petcock located underneath the tank.
LUBRICATION
This is an oilless product and DOES NOT require lubrication to operate.
MOISTURE IN COMPRESSED AIR
Moisture in compressed air will forminto droplets as itcomes from an air compressor pump.When humidity is high or when
a compressor is in continuous use for an extended period of time, this moisture will collect in the tank. When using a paint
spray or sandblast gun, this water will be carried from the tank through the hose,and out of the gun as droplets mixed with
the spray material.
IMPORTANT: This condensationwillcause waterspotsin a paintjob, especially when spraying other than waterbased paints.
If sandblasting,itwill cause the sand tocase and clog the gun renderingit ineffective. A filter in the air line (MP3105), located
as near tothe gun as possible, willhelp eliminate this moisture.
SAFETY VALVE
Do not remove or attempt to adjust the safety valve!
This valve should be checked underpressureoccasionally bypullingthe ringby hand.If air leaks after ring has been released,
or valve is stuck and cannotbe actuated byring,itMUST be replaced.
REGULATORKNOB(figure 5)

MAINTENANCE
WARNING!
Disconnect power source then release all pressure from the system before attempting to install, service, relocate or perform any
maintenance.
Check compressor often for any visibleproblems and follow maintenanceprocedures each time compressor is used.

1. Pull ringon safety valve and allowit to snap back to normal position.
WARNING!
Safety valve must be replaced if it cannot be actuated or it leaks air after ring is released.
2. Turn compressor off and release pressure from system. Drain moisture from tank by opening drain cock underneath tank.
3. Clean dust and dirt from motor, tank, and airlines and pump cooling fins while compressor is still OFF.
IMPORTANT: Locate unit as far from spraying area, as hose will allow preventing overspray from clogging filter.
LUBRICATION
This is an oillesstype compressor requiring no lubrication.
THERMAL OVERLOAD PROTECTOR compressor is equipped with an automatic reset thermal overload protector; which will shut off
motor if it becomes overheated.
If thermal overload protector shuts motor OFF frequently, look for the following causes.
1. Low voltage.
2. Clogged air filter.
3. Lack of proper ventilation.
CAUTION!
If the thermal overload protector is actuated, the motor must be allowed to cool down before start-up is possible. The motor will automatically
restart without warning if left plugged into electrical outlet and unit is turned on.
STORAGE
1. When not in use, store hose and compressor in a cool dry place.
2. Drain tank of moisture.
Disconnect hose and hang open ends down to allow any moisture to drain.
